Add texture to any STL

A free tool to emboss or engrave surface texture onto a 3D model before you print it: geometric patterns, knurling, wood and leather grain, or your own logo. Everything runs in your browser, so your model never leaves your computer.

How to add texture to an STL

1. Load your model (STL, OBJ, 3MF or PLY) by dropping it anywhere on the page, or start from the demo.
2. Click a face to choose where the texture goes, or use “Select all faces” for the whole surface. Keep the bottom flat so the print still sticks to the bed.
3. Pick a texture. Geometric patterns bake as exact, watertight CAD geometry; photo textures such as wood or leather use fine displacement. You can also upload an SVG logo or a grayscale PNG height map.
4. Set the depth (emboss out or engrave in), the zoom (how big the pattern is), rotation, and detail.
5. Apply, then export a printable STL, OBJ, 3MF or PLY.

Geometric patterns vs. photo textures

Geometric presets (knurling, hexagons, diamond plate, ridges, studs) are generated as real, watertight solids, so the result stays a clean, sliceable mesh at any size. Photo textures (wood grain, leather, fur) are grayscale height maps: light areas rise, dark areas recede, and the surface is subdivided finely enough to carry the detail. The Detail control trades file size for how sharply that detail is carved.

Add a logo to an STL

Upload an SVG and it becomes crisp, vector-accurate raised (or recessed) geometry, ideal for a logo, name plate or maker’s mark. A PNG or JPG works too, read as a height map where white is the raised part.

Hide 3D print layer lines

A shallow all-over texture such as knurling, fine ridges or a subtle noise breaks up flat walls so the eye stops reading horizontal layer lines. Apply it to the side faces, keep the depth small (0.3 to 0.8 mm), and the print looks intentionally finished rather than striped.
